Review on Chicago Latrobe High Speed Extra Long Notched by Joshua Castillo

This is an amazing drill bit made in the USA. I bought it as "last" for $8! 90% discount! To turn the tip 1" on his lathe to 1/2" to fit my low torque and high torque drill bit. I drilled holes in several 6" laminated wood joists from 2x8 glued and screwed together. I used to mess up 2 drill bits when hitting hardened screws. This bit went right through the screws without missing! Drilled 12 holes in 2 joists. Great drill bit !
